Fading of Z Cam. This outburst is similar to
the previous one (http://aibn55.astro.uni-bonn:8000/~jpietz/pix/zcam.gif):

	- Rise up to 11mag (JD2449693 and 2449730)
	- Slow fade to 11.9mag (~20days)
	- Minor rise up to 11.5mag
	- Fading to minimum (13.1mag)

If this second rise is real, the timescale (~20days) between
the primary and the second maximum is of same order as the
duration of the outburst cycle before the onset of the 'peculiar'
outbursts. (The next outburst will probably occur at the end of this
month.)
